What is the Average 12kW Solar System Cost?
The average cost of a 12kW solar system stays between $30,000 and $35,000 before any incentives and rebates. This price includes equipment, installation, and other costs. Remember, there’s a 30% Residential Clean Energy Credit, so the effective price stays around $21,000 and $24,500. Solar and local solar rebates and incentives can cut those costs even further.
Components of a 12kW Solar System
A 12kW solar system typically consists of solar panels, a charge controller, an inverter, mounting structure, cables, and a battery bank for storing energy. These are explained as follows:
Solar Panels: These are the primary components of a solar system and convert sunlight into DC electricity. Depending on the individual wattage of the panels, a 12kW system would need a certain number of panels to deliver the required output.
Charge Controller: Also known as a charge regulator, it regulates the current between solar panels and the battery. Its primary task is to maintain an optimal flow and prevent overcharging and potential battery damage.
Inverter: This device converts the DC electricity from solar panels into AC electricity. Then, it passes the current to the main power grid to keep home appliances running.
Mounting Structure: It securely holds the solar panels to the ground or roof and ensures their proper orientation toward the sun. In other words, it ensures that sunlight falls properly on the panels and converts it into usable electricity.
Cables: You’ll see two types of cables in a solar system: AC and DC cables. The latter carries DC electricity from solar panels to the charge controller, while the former carries electricity from the inverter to the electric grid.
Battery Bank (Optional): It’s a part of an off-grid solar system that stores the energy it generates. This can be an emergency source to power your household appliances when the sun is not shining.
12kW Solar System Costs: Detailed Breakdown
As of 2025, the average cost of a 12kW solar system ranges between $30,000 and $35,000, excluding incentives and rebates. Other than the 30% federal tax rebate, there are other incentives like property tax exemptions, sales tax exemptions, and others, which vary from state to state. Other than the rebates, many factors can significantly vary the prices of solar systems:
Location: How much does a 12kW solar system costs is determined by two location-based factors: the amount of sunlight you receive and electricity costs in your area. In certain states like California, Hawaii, and New York, the electricity rates are a bit high, so going solar saves a large chunk every month. Besides, states Arizona and New Mexico receive up to 8 peak sun hours, so you’ll need fewer panels there.
Panel Quality and Type: The equipment and solar panel costs probably encompass the major chunk of your investment. Prices vary from one manufacturer to another and the type. There are three types of solar panels: monocrystalline, thin-film, and polycrystalline. Monocrystalline panels are the most efficient, hence the costliest, followed by polycrystalline, and thin-film.
Installation: The installation costs vary from one vendor to another due to the varying labor costs. Roof/ground type, height, and pitch can influence the costs. Any installation complexities or difficult-to-access locations may incur additional expenses.
Solar System Size: The cost of a solar system is directly proportional to its size. The more solar panels you need to power your home appliances, the more expensive your solar system will be. The cost also depends on roof size and angle, location, and energy usage.
House Energy Needs: A typical US household consumes around 889kWh of energy monthly and 10,791kWh yearly. However, the numbers vary with your home size, number of people, and available appliances.
Here’s a detailed breakdown of how much a 12kW solar systems installations cost:
Component |
Estimated Cost Range |
Solar Panels |
$16,000 - $18,000 |
Mounting Hardware |
$3,000 - $3,500 |
Inverters |
$3,500 - $4,500 |
Installation Labor |
$5,500 - $6,000 |
Permits and Inspection Fees |
$1,000 - $1,500 |
Miscellaneous |
$1,000 - $1,500 |
Total |
$30,000-$35,000 |
Unlike this, with Jackery Solar Generators, you avoid installation, mounting hardware, permit, and inspection fees. That is, you save around 30% of the total cost incurred on the solar power system. Besides, these are reliable and also suitable for your off-grid living.
12kW Solar System with Battery Storage Cost
A 12kW solar system with battery storage typically costs between $42,000 and $53,000. It costs you around $12,000 and $18,000 extra, considering the typical battery cost is around $1,000 to $1,500 per kWh. With a 30% federal tax credit applied, the solar system would cost you between $29,000 and $37,000. Look for state-wise incentives to bring the price further down.
A few other factors influence the cost when you add battery storage to your 12kW solar system, which is:
Battery Type: The type of battery also dictates the total 12kW solar system cost you incur. Two of the most popular battery types are lead-acid and lithium-ion. The former is cheaper in comparison and is common in most solar system installations. However, it isn’t very efficient, as its longevity demands regular maintenance.
On the other hand, a Li-ion battery is more efficient. It charges faster, requires less maintenance, has better capacity, and a greater depth of discharge (80%). However, it costs more than lead-acid batteries.
Brand: Batteries from certain brands cost more with the offered superior quality and the faith that comes with the brand names. Many reliable yet affordable batteries are out there, and you can opt for them as well.
Inverter Type: The cost of batteries also varies with the type of inverter installed in your solar system. If you don’t have a battery-ready hybrid inverter, the cost will be significantly high as you need to invest in a brand-new inverter. You may also get around with additional wiring and minor changes, but it’s subjective to the inverter type.
What Does a Residential 12kW Solar System Cost?
The average cost per watt for residential solar installations in the US ranges between $2.50 and $3.50 per watt. So, a 12kW solar system would cost you between $30,000 and $40,000, excluding the rebates and incentives.
Type of 12kW solar systems |
Costs |
Grid-Tie Roof Top System |
$25,080 |
Off-Grid Roof Top System |
$37,320 |
Hybrid Roof Top System |
$59,280 |
However, the prices vary due to multiple factors like location, component and installation costs, labor, and others.

How Much Can I Save With a 12kW Solar Power System?
An average US homeowner will save between $700 and $1,200 every quarterly bill, or around $4,500 annually. However, the numbers vary on multiple factors: your location, electricity rates in your area, and installation costs.
Let’s assume you stay in California, which receives around 7 peak sun hours daily. So, a 12kW solar power system produces = 12kW × 7 = 84kWh in a day and 2520kWh in a month.
Now, considering the average electricity price in California is 32.68 cents/kWh, your daily savings account to = Total energy generated × Electricity prices per kWh = 2,520 × 0.32 = $800 per month.
The calculation is performed considering you consume 2,520kWh of electricity every month. To obtain the actual value, use the formula:
Appliance wattage (W) x Usage hours per day = Watt-hours (Wh) per day
Appliance wattage is the sum of the wattage of appliances in your house. So, consider that you have a refrigerator (800W), dishwasher (1600W), central AC (3000W), and microwave (1200W).
The sum of wattages or total wattage consumption stands at 6,600W. Let’s assume they run for around 10 hours a day, So Wh = 6,600W x 10H = 66,000Wh or 66kWh.
Total Savings = 66kWh × 0.32 = $21.12 per day or $633.6 per month.
